   The car just died while going 55mph on the highway. Complete shutdown but luckily both the steering and brakes worked. After stopping it wouldn’t start again. I had my three children in the car aged [XXX], [XXX], and [XXX]. It was a horrific experience. GMC did some repairs to the engine that took over two months and then the car had a few more warnings pop up just a few weeks later. GMC now says there is a misfiring in one of the positions. I’m terrified of driving this car…

   While driving about 70 mph in the express lanes, the vehicle suddenly lost power and drifted like it went into neutral. There were no warning symbols. The vehicle could not restart even while coasting. After stopping, it locked itself in park and would not shift out of park. My family and I were trapped on the express lanes for over an hour in a dangerous location. The vehicle stayed stuck in park even on the tow truck. The dealer confirmed metal in the oil filter, a blown…

   I own a 2023 GMC Yukon Denali. In Nov. 2023, at about 4,000 miles, the vehicle suffered a complete engine and electrical failure at highway speed while I was traveling with my husband and three small children. It suddenly lost all power in the fast lane, including acceleration and engine function. Steering became extremely heavy, consistent with loss of power steering assist, and the electronics shut down. We had to guide the vehicle across traffic while coasting downhill to…

   Following a catastrophic engine failure in my 2023 GMC Yukon XL Denali, I discovered that the vehicle could not be shifted into neutral once the engine failed. This prevented the vehicle from being moved out of traffic if it had stopped in an active lane. The inability to place the vehicle into neutral after a loss-of-power event creates a serious safety hazard, particularly on high-speed roadways. In the event of a failure occurring in traffic, occupants may be left…

    There have been several issues for which I had to take my vehicle to the dealer. I did the engine oil recall. Then 4 months later my engine was destroyed. I’ve had several issues with oil leaks. I had an issue with my running boards a few times. And I’ve had an ongoing issue that the dealer hasn’t been able to fix - a water leak (I believe stemming from the moonroof), water gets into my vehicle, on my floorboard, and behind the dash. I’ve called to record these incidents…
